"Mechanical work processes have grown immensely, both in number and in scope, and it is obvious that their automatism, controlled and watched as it is by man, in turn has its effect on man. The power that man gains by his automatic tools gains power over him. He is compelled to give them his thought and his attention. Inasmuch as he works with automatic tools, his work becomes mechanical and repetitious with machinelike uniformity. Automatism clutches the operator and never relinquishes its grip on him. To the consequences of this we shall return again and again."
